Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it is understood that "first" and "second" are only used for convenience of expression and should not be understood as limitations to the embodiments of the present invention, and the following embodiments do not describe any more.

The terms of direction and position in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., refer to the direction and position of the attached drawings. Accordingly, the use of directional and positional terms is intended to illustrate and understand the present invention and is not intended to limit the scope of the invention.

Example (b): as shown in fig. 1, fig. 2, fig. 3, the utility model relates to a hoist and mount operation prevents hindering people's system, including hoist and mount region 1, hoist and mount region 1 one side and articulate there is regional door 2, fixed mounting has latch mechanism on the regional door 2, latch mechanism output is just to spacing module 3 of door, spacing module 3 fixed mounting is in hoist and mount region 1 side, hoist and mount region 1 internal fixed mounting has human infrared induction module 4, threshold spacing module 3 and the parallelly connected electric connection of human infrared induction module 4, and threshold spacing module 3 and human infrared induction module 4 respectively with the parallelly connected electric connection of alarm module.

Wherein, the hoisting area 1 is formed by combining four guardrails.

Wherein, latched device includes fixed plate 5, and fixed plate 5 fixed mounting is on regional door 2, and fixed plate 5 runs through sliding connection has T type pole 6, and fixed compression spring 7 that is equipped with between 6 one end of T type pole and the fixed plate 5, compression spring 7 cover are on T type pole 6, and 6 other ends of T type pole articulate has swing post 8, and 8 sides of swing post are provided with locating hole board 9, and locating hole board 9 is fixed on hoist and mount region 1.
